We follow the SMEFT framework to study the new physics effects to the Higgs-top coupling at high scales. We adopt the Warsaw basis of operators [1]} and focus on two-fermion operators, leading to contributions to \(t\bar{t}h\)  production at the LHC which are relatively unconstrained
\(\mathcal {O}_{t\phi } & =(H^\dagger H)(\bar{Q}t)\tilde{H}+\text{h.c.}\,, \\\mathcal {O}_{tG} & =g_s(\bar{Q}\sigma ^{\mu \nu }T_A t)\tilde{H}G_{\mu \nu }^A+\text{h.c.}\,.\)
